9 Claims. (Cl. 15118) My invention relates to a mop, more particularlyfor use in mopping oors or the like, and the objects of my inventionare:

First, to provide a mop of this class having a group of mop yarnstationarily fixed to the mop head, and a secondary group of mop yarnpivtally mounted below the first-mentioned group, providing optional useof the mop as an oil mop or a dry mop, as desired;

Second, to provide a mop of this class which may be convertedfrom an oilmop to a dry mop with a minimum amount of effort;

Third, to provide a mop of this class having a novel grommet forconnecting the handle thereof to the mop head;

Fourth, to provide a mop of this class having a novel detent means forholding a pivoted group of mop yarn in certain relationship to a groupof mop yarn stationarily connected to the mop head of said mop;

Fifth, to provide a mop of this class which is particularly adapted tooperate in confined places;

Sixth, to provide a mop of this class which is very light and compact inproportion to its utilitarian functions'as either an oil mop or a drymop; and

Seventh, to provide a mop of this class which is very simple andeconomical of construction, efcient in operation, and which will notreadily deteriorate or get out of order.

With these and other objects in view, as will appear hereinafter, myinvention consists of certain novel features of construction,combination and arrangement of parts and portions, as will behereinafter described in detail and particularly set forth in theappended claims, reference being had to the accompanying drawings and tothe characters of reference thereon, forming a part of this application,in which:

Fig. l is a top or plan view of my mop Fig. 2

` is a side elevational View thereof, showing a portion of the handlebroken away; Fig. 3 is an enlarged fragmentary sectional view, takenfrom the line 3-3 of Fig. l, showing the mop yarn of the mop omitted tofacilitate the illustration; and Fig. 4 is an enlarged fragmentarysectional view, taken from the line 4-4 of Fig. 3.

Similar characters of reference refer to similar parts and portionsthroughout the several views of the drawings.

The mop head I, handle grommet 2, mop head cover 3, yarn cape 4, elastic5, yarn arm 6, yarn arm cover 'I, mop yarn groups 8 and 9, straps II)and II, and the handle I2, constitute the principal parts and portionsof my mop.

The mop head I is a substantially rigid'member, preferably of ellipticalshape, and this mop head I is provided with central opening Ia therein,in which the resilient rubber grommet 2 is fixed at its flange portionIb by means of the annular ring ic, which is pressed into the enlargeddiameter portion Id of the opening Ia. Thek resilient grommet 2 ispreferably made of rubber or the like, and frictionally engages theouter side of thev handle l2 in surrounding relationship therewith, nearthe normally lower end thereof, as shown best in Fig. 3 of the drawings.

The upper side of the mop head I curves downwardly and outwardly towardthe outer edge thereof, and is engaged by the resilient fabric yarn cape4, which is provided with a resilient bead 4a substantially inwardly andabove the outer edge of the mop head I, and supported on this yarn cape4 is the mop yarn group 8, as shown best in Figs. 1 and 2 of thedrawings. `This mop lyarn group 8, fixed to the yarn cape 4, extendsoutwardly and downwardlyfrom the mop head I, and pivoted to the middleportion of the yarn cape 4 is the arm 6, which supports the yarn group 9on an axis laterally of the ,longitudinal axis of the mop head I. y

The arm 6 is preferablylmade of wire or the like, and is U shaped, aslshown in'Fig. 4 of the drawings, and is provided with pivotal bearingportions 6a and Sb, which are held within the yarn arm cover 1 at theseam connection 1a, which supports the yarn arm cover 1 on the lowerside of the yarn cape 4. Extending outwardly from the bearing portions6a and 6b is the lever portion Bc, over which the elastic strap 5extends. This elastic strap 5 is fixed at its opposite ends 5a and 5b tothe lower side of the yarn cape 4, and acts as a detent over the leverportion 6c for maintaining said arm 6 in certain adjacent relationshipto either end of the mop head I, below the yarn group 8.V

It will be noted that the yarny group 9 is supported on the yarnarmcover "I, which'` is a fabric cover, shown in Fig. 3 of the'drawings,and that opposite sides of the yarn group 9 may be used for differentpurposes, as desired.' One side of the yarn group S may be used as anoil mop for oiling floors, while the opposite side of the yarn group 9may be a dry mop for dusting. It will be noted that the pivotalmovementA of the yarn group 9 on the arm 6 permits opposite sides Yofsaid yarn group 9 to be employed optionally, and the respective portionof the yarn group 8V exposed downwardly cooperates with each' side ofthe yarn group9"in certain positions.

It will be noted that a portion of the yarn group 8, from the middle ofthe mop head i toward one end, may be used as an oil mop, while theportion from the middle of the mop head toward the opposite ends thereofmay be used as a dry mop.

The straps IB and Il are secured to the arm 6, and provide meansengageable with a persons foot for pivoting the arm 6 from one end tothe other of the mop head l, as indicated by the arrows A and B, in Fig.2 of the drawings.

The handle I2, in its connection with the resilient grommet 2, ismovable in any desired direction, as indicated by dash lines in Fig. 3of the drawings, and may be used to support the mop and move the sameduring the use of the straps lo and Il, hereinbefore described.

The operation of my mop is substantially as follows:

When the mop is used as an oil mop, one side of the yarn group 9 isdisposed downwardly by certain'disposition of the yarn arm 6, and theadjacent portion of the yarn group 8, as hereinbefore described, iscooperative. Thus, one half of the yarn group 8, beyond the pivotalconnection ofthe arm B, may be oiled, and the other half may remaindry.y Correspondingly, the opposite side of the yarn group 9 may be dry,so that Isimple pivotal movement of the arm 6 converts the mop from anoil mop to a dry mop, or from a dry mop to an oil mop, as desired. `Theelastic 5 slides over the lever 6c during movenient of the lever 6, andmaintains the same in certain adjusted position during the use of themop. When it is desired to pivot the yarn group 9 lfrom one position tothe other, as indicated by the arrows A and B, the straps l0 and Ilafford a holding means, which may be engaged by a persons foot, so thatsimple movement of the handle in a lateral direction causes the strapsIVD and ll to pull the arm 6 in a direction as indicated by either ofthe arrows A or B, causing the lever portion 6c to traverse theelastic5.

A s shown in Fig. 2 of the drawings, the oiled side of the yarn group Bbears against the oiled portion of the yarn group 8 and the dry side ofthe yarn group Bprovides a continuation of the lower-mopping surface ofthe Inop, together with therdry portion of the yarn group 8.

Though I have Shown and described a particuiar construction,combination, and arrangement cf parts and portions. I do not wish t0 belimited to this particular construction, combination and arrangement butdesire t0 .include in the scope .0f mv invention the construction.combination and arrangement substantially as set forth in the appendedclaims.
